Magnetic 2D Materials: Studying and Manipulating Ordered Spins in Flatland*

Magnetic 2D materials have attracted a pivotal attention thanks to both fundamental breakthrough studies in low-dimensional magnetism and also device applications. The potential to fabricate ultra-thin magnetic devices paves the way to change the miniaturization paradigm of the limitations of magnetic-enabled microelectronics and integrated photonics. However, the basic requirement to design such optoelectronic devices is to have a profound understanding of fundamental properties such as the magnetic ground state or the complex dielectric function of these systems. Here, I will address the major advancements in this field, showcasing the complexity of magnetic 2D materials through the results of spectroscopic experiments.
